Our exclusive with Buffett

How you could’ve turned $114 into $400,000 with a simple long-term investment: Many of us know the magic of investing money in the stock market — just letting it sit and watching it grow — but few of us really grasp just how powerfully enriching this can be. Not surprisingly, Warren Buffett, the world’s greatest investor, has a vivid example of this which he shared with Yahoo Finance Editor in Chief Andy Serwer.

But it’s his steadfast belief in the U.S. economy that ultimately bolsters Buffett’s view on our financial markets. And why Buffett doesn’t fear the sometimes scary volatility that can come to the market.

Buffett: Women make me ‘very optimistic’ about this country: Buffett is bullish on the potential of women in the U.S. to boost the economy. “I have two sisters that are absolutely smart as I am and better personalities,” Buffett told Yahoo Finance’s Editor in Chief Andy Serwer in a wide-ranging interview.
